Hi Steve!

yes.

yes. as long as the method does not use instance or static variables
> 3. The method called above has local variables which are used in
> processing the above, still safe ?
yes.
> 4. The method returns a result and the doGet continues through methods

right.

instance and static (i.e. class) variables.
